With an hourly output of 7,850 kW and peak at 140 km/h, the 1972 Re 6/6, which was first commissioned in Switzerland, is still one of the strongest locomotives in Switzerland. In order to achieve higher cornering speeds, the BoâBoâ axis sequence was given preference over the usual CoâCoâ. Also in terms of wheel tread and track wear, the more complex three bogies â enhanced by the Re 4/4 II â proved to be very advantageous. The Re 6/6 can be found everywhere, whether in individual traction, in multiple control under oneself and above all in goods traffic mostly as so-called Re 10/10 together with a Re 4/4 II or Re 4/4 III.This text is machine translated.
